Title: High frequency welding equipment for composite sheet
Inventor: TANIMURA TOSHIKAZU
IPC: B29L31/58
Filed: 1987-09-22
Abstract: PURPOSE:To prevent the excess of an interposing pressure and to improve a welding strength as well by fitting an electrode via an elastic expansion means to one part of a substrate and providing the guide member serving for a stopper as well on both substrates. CONSTITUTION:A lamination body 3 is interposed and pressed between electrodes 2a, 2b. At this time, The electrodes 2a, 2b are guided so as to move on the same straight line by fitting the projecting part 5b of a guide member 5 serving for a stopper as well into the recessed part 5a thereof. The most approaching position of the electrodes 2a, 2b is regulated by the member 5 and no further approach is made. The interposing force increases with the electrodes 2a, 2b being approached and the degree of compressing the spring 4b of the base part of the electrode 2a being increased. However the electrodes 2a, 2b do not approach by exceeding the regulated position of the member 5, interposing without excess and ununiform pressures, exerting a high frequency voltage between the electrodes 2a, 2b, generating a heat inside the lamination body 3 and executing the deposition. Consequently external appearance is not spoiled nor deposition strength reduced.

Title: Drive controller of brushless motor and electric equipment using the same
Inventor: NAKAYAMA TAKAHIRO
IPC: H02P6/06
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a drive and controller of a brushless motor which can start up a motor stably with high reliability and never decrease the motor efficiency even during the steady rotation by satisfying the optimum current carrying phase and also provide an electric motor using such a driver and controller. SOLUTION: A driver and controller of a brushless motor is provided with a phase detecting means 6 which can adjust a phase by adjusting a reference voltage. After the operation is switched from a synchronous operation to a position detecting operation, a current carrying phase is switched at a point of change in a position detection signal until the position detection signal is found stable. After the position detection signal becomes stable, the current carrying phase is switched earlier than a point of change in the position detection signal. As a result, the operation can be shifted smoothly from the synchronous operation to the position detecting operation and a motor can be started up with high reliability. Moreover, even during steady rotation, the decline in the motor efficiency can be prevented by satisfying the optimum current carrying phase.

Title: Freezer device
Inventor: NAKAYAMA ISAMU
IPC: F25B1/00
Filed: 1989-09-14
Abstract: PURPOSE:To control an over-heating degree of a sucked gas refrigerant to its wet side and decrease a temperature of a discharged gas refrigerant by a method wherein when a temperature of discharged gas refrigerant from a compressor exceeds a reference temperature, a compression capacity of the compressor is restricted and at the same time a degree of opening of an electrical expansion valve is fixed to a degree of opening before modifying a compression capacity. CONSTITUTION:When a sensing temperature signal Tot at a discharged gas temperature sensor 40 exceeds 120 deg.C, a degree of opening of each of the first electrical expansion valves 25 and 24 is fixed and at the same time it is vertically controlled, a reduction of an input current for a compressor 1 caused by a reduction of a compression capacity and a fixing of a degree of opening of each of the first electrical expansion valves 23 and 24 are controlled. As a result, an amount of gas refrigerant supplied to both indoor heat exchangers 5 and 6 is reduced and at the same time its degree of over-heating is also reduced and a suction gas refrigerant temperature at the compressor 1 is transferred to its wet side, so that a discharged gas refrigerant temperature is lowered and each of the controlling operations is continued until its temperature reaches a recovery temperature 95 deg.C. When Tot is less than 95 deg.C, a load responding control and an over-heating degree control are restarted, its operation is continued while a coil over-heating of the compressor 1 being restricted and then an air conditioning performance is improved.
